Steel Prop Production: Thread Rolling, Punching and Tube Welding

Updated 3 November 2026

A steel prop manufacturing plan should start with separate drawings for the inner tube, outer tube and the parts joined to them. Thread rolling, hole punching and welding perform different jobs. The route for each component depends on its design; do not assume that every tube passes through all three machines in the same order. Match each operation to the drawing before planning how equipment will work together.

Thread rolling: define the thread before the machine

The steel prop thread rolling machine offers adjustable rolling pressure and depth, with automatic feeding and unloading. The catalogue lists material diameters from 30 to 90 mm and a minimum workpiece wall thickness of 2 mm. Its chipless forming process reduces material waste. Supply the required thread dimensions, tube material and wall thickness when discussing tooling. Confirm the intended finished thread rather than selecting equipment only by the starting tube diameter.

Punching: specify the hole pattern

The JS-GZC-CK steel prop punching machine uses servo feeding and adjustable hole spacing. It punches two workpieces per cycle and combines PLC control with a human-machine interface. Listed tube lengths are 0.5–3 m, with wall thicknesses of 2–3.5 mm. Provide a drawing that identifies hole size, spacing and position from the tube end. Include each hole pattern you expect to manufacture so that tooling and setup requirements can be reviewed.

Tube welding: match the fixture to the assembly

The JS-GZC-HJ inner/outer tube welding machine uses tooling configured for the steel prop tube being produced. It includes automatic pipe, base plate and prop nut feeding with automatic welding, plus fine adjustment of welding angle and height. The listed pipe diameter range is 48.3–60 mm and the length range is 0.5–3 m. Identify which parts are attached to each tube and provide their dimensions and weld locations.

Plan component flow between operations

Compare the size ranges of all selected machines against the same component list. The ranges differ, so compatibility with one machine does not establish compatibility with the next. Review where tubes will be stored, how they will reach each station and where finished assemblies will be checked. Base the sequence on your drawings and production plan, and identify which transfers will remain manual.

Prepare a useful equipment enquiry

For each component, provide a drawing, material specification, tube dimensions and required production quantity. Add thread details, hole patterns and weld locations where relevant. State the output you need per shift so that the proposed process can be assessed against your target. Ask which tooling and settings are needed when changing products, and agree on representative samples for evaluating the finished threads, holes and welded assemblies.
